Vibration Damping Bracket Locking Groove Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration damping devices with a bracket member fitted into a tube-shaped first mounting member often experience a decrease in positioning effect, leading to the risk of the bracket member falling out, due to the design of engaging parts which compromise the fitting mechanism.
Innovation Solution
A vibration damping device with a tubular first mounting member featuring a projecting part and a locking groove covered by a rubber coating layer, where the engaging projection of the bracket member is locked into the groove, ensuring stable positioning by increasing the pressed surface area and preventing the bracket member from falling out.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If engaging parts are provided on the rubber coating layer and bracket member to prevent falling out, then the reliability of connection is improved, but the positioning effect by fitting is decreased
Solution Approach 1:
The invention divides the connection function into two distinct mechanisms: (1) a positioning function achieved by the fitting of the bracket member into the tube-shaped first mounting member, and (2) a prevention-of-falling-out function achieved by the engaging parts. This segmentation allows each mechanism to be optimized independently, with the fitting providing precise positioning and the engaging parts providing secure retention without interfering with the positioning precision.
Solution Approach 2:
The rubber coating layer serves as an intermediary element between the bracket member and the first mounting member. The engaging parts are formed on this rubber coating layer, allowing the locking function to be implemented without directly modifying the metal surfaces, thereby preserving the positioning effect of the fitting while adding the retention function.
2Manufacturing precision
If the bracket member is fit into the first mounting member to obtain positioning effect, then the positioning precision is improved, but the risk of falling out increases
Solution Approach 1:
The connection function is segmented into positioning (achieved by fitting) and retention (achieved by engaging parts). The engaging projection and engaging groove are designed to work independently from the fitting mechanism, allowing the bracket member to be precisely positioned by the fit while the engaging parts prevent falling out.
Solution Approach 2:
The engaging parts are designed to engage automatically when the bracket member is fitted into the first mounting member. The engaging projection fits into the engaging groove as a preliminary action during assembly, establishing the retention function before any potential falling out can occur.

AI summary
A vibration damping device including: first and second mounting members; a main rubber elastic body elastically connecting the two members; and a bracket member fit into the first mounting member. A projecting part projects outward from a circumference of the first mounting member, and includes a locking groove whose inner surface is covered by a rubber coating layer and has a locking part on its side wall inner surface. An engaging projection projecting from the bracket member is fit into the locking groove, and a projection tip surface of the engaging projection is abutted on a bottom wall inner surface of the locking groove. A side surface of the engaging projection is locked to the locking part so as to constitute a positioning member that positions the first mounting member and the bracket member to each other.
